I just put a set of DD2's in and have a edge comp but haven't tapped the wire (so it is the same as the ez). DD2's are rated the same as edm 1. 5 but have heard that the edms run better. I'm not sure about what DF said on the clutch, I just put the injectors in last night but the stock clutch hasn't slipped yet. I've heard people say that the stock will hold for a while but will eventually start slipping. Doesn't matter when it goes for me, I have a SB con ofe sitting in the living room floor for when I need it! Will run stock till it slips.
So far I like the combination. Haven't pulled with this set up yet but could only get to 1275 on the pyro with completly stock exhaust and drop in K+N air filter. Will eventually put 4" exhaust and scotty air in before I tap the wire on the comp.
